The analytic results obtained from the PCT evaluations revealed that the most limiting accident was the case with a break at the Main Steamline Outside Containment. Its PCT was 1289.15 ℉, which is much below the upper temperature limit of 2200℉ set by the nuclear regulatory authority. The most limiting accident for the minimum water level measured outside the core shroud is the case with a break at the High Pressure Core Flooder Line, the minimum water level drops to 18.4 ft. For this case, even though the water level has dropped to 11.6 ft below the top of the active fuel, the reactor core was still completely covered by the two-phase water.

The anode structure of CI-LIGBT is optimized by numerical simulation, and it is pointed out that segmented p〓 anode region surrounded by n〓 anode region is the key to improve the ability of current limiting, and the more deeper the n〓 anode junction relative to the p〓 anode junction, the more powerful the ability of current limiting is. The affection of the breakdown voltage BV〓 of the reverse biased p〓n〓 junction and the sample resistance upon the latching current, the latching voltage and the on-state voltage have been studied, and it is indicated that the tradeoff between the on-state voltage and the latching characteristics is the excellentest when BV〓 is 1. 1V so that its on-state voltage can be just only 0.6V higher than conventional LIGBT. It is also found that this device is especially suit to high temperature environment. Based on X. B. Chen's surface voltage sustaining structure using optimized variational lateral doping and Ludikhuize's multiple floating rings structure, high voltage LIGBT and is studied in this paper.

Based on the results, it has found that six distinct layers can be identified from lateral to medial in the olfactory bulbs, and the adults have more cells than the subadults. Ventricles of the adults take up larger vacuity, have richer choroids plexus, and primordial pallium and primordial hippocampus of them are more developed than the subadults, in which the primordial piriform is well-developed. Ventral to the primordial hippocampus, there is a septal area which can not be divided into medial and lateral parts in both adults and subadults, nor there is lateral limiting sulcus to separate the primordial piriform and the corpus striatum, but only in the subadults, a medial limiting sulcus can be clearly identified to separate the primordial hippocampus and the septal area. Besides, the corpus striatum of Onychodactylus fischeri is paleostriatum. The cell group that located at two sides of the third ventricle is amygdale, and shape and size of neurons within the telencephalon are poorly differentiation.
